On October 24, a gas flash accident occurred in a residential building in Dalian, Liaoning Province, killing 2 people and injuring 7 people, and the cause of the accident is under investigation.
On October 21, the grief caused by the gas explosion accident in Shenyang has not yet dissipated, and a similar gas explosion accident has occurred. According to the news of "Shenyang Release" on the evening of the 22nd, the number of deaths in the gas explosion in Shenyang has reached 5 people, and 47 people have been injured. In the cold winter, the explosion also caused more than 15,000 nearby households to lose power.
According to the statistics of the "National Gas Accident Analysis Report", in the first half of 2021, there were 544 gas accidents in China (excluding Hong Kong, Macao and Taiwan), resulting in 71 deaths and 412 injuries; accidents were distributed in 31 provinces and 215 cities across the country.
Gas explosion "pain and pain": the safety of old residential areas attracts attention
With the continuous development of the city, those communities built as early as the 80s, 90s and even earlier have slowly become what we call old communities, and the fire safety hazards in the old residential areas are like a "time bomb", which always threatens the personal and property safety of residents.
The "Household Gas Burner Safety Regulations" clearly stipulates that from the date of sale, the service life of the gas stove is 8 years, and the new standard in 2011 requires that the gas stove must have a flameout protection function; the service life of the gas water heater is 8 years, and the use of the service life will lead to the aging of components, increasing the possibility of air leakage, resulting in exhaust gas backfilling, flameout, carbon monoxide poisoning, explosion, etc. The service life of the hose is generally about 18 months, and the hose that has been used for overtime should be replaced in time to prevent the hose from aging and leaking.
Gas explosions can have serious social consequences and leave people in a state of anxiety. Even after many people witnessed the gas explosion, they had gas phobia, and the gas stove at home did not dare to use it. Why are gas explosions frequent? How can it be prevented?
1. When using gas, pay attention to indoor ventilation
Users must develop the habit of indoor ventilation, let the air circulate, and avoid personnel injury accidents caused by lack of oxygen.
2. Close the "two valves" after using the gas
Every time the gas is used, not only the gas appliance switch is turned off, but also the corner valve of the gas line or cylinder.
3, gas hose to "two tight"
The connection at both ends of the gas hose should be fixed and tightened with a throat code to avoid accidents caused by loose or falling off.
4. When the gas leaks, the burner switch should be turned off immediately
If you find a gas leak, you must hold your breath, keep your composure, and close the valve first.
5. Do not switch or use electrical appliances when the gas leaks
Turning on and off any appliance can produce tiny sparks that can cause an explosion.
The risk of gas leakage is not prevented. Install combustible gas detectors to safely guard the "pyrotechnic gas" and keep the family safe and worry-free.
China Consumption Cloud NB stand-alone combustible gas detector, can detect the concentration of combustible gases in the air in real time, once the alarm value of the detector is reached, it will immediately issue a sound and light alarm, and send the police information to up to 5 contacts through mobile phones, text messages and APP.
At the same time, the combustible gas detector can also cooperate with the installation of solenoid valve manipulator, when a gas leakage alarm occurs, the detector can immediately control the solenoid valve manipulator to automatically turn off the gas, even if no one is on the scene, it can also quickly eliminate the hidden dangers of accidents.
The successive accidents are really painful, and I hope that the relevant departments can do a good job in dealing with the aftermath, and I also hope that similar tragedies will not be staged again.
